Directions

Preheat grill to medium-high and grease grates well. Pat steaks dry with paper towel, and season with salt and pepper.

Grill steak for 4 to 5 minutes per side for medium rare, or cook to your liking. Let steak rest for 10 minutes.

Toss red onion slices with olive oil. Grill onions for 2 to 3 minutes per side, or until tender. Once steak has rested, slice thinly against the grain.

Grill baguette cut side down for 30 seconds, or until lightly marked. Spread tapenade on half of the baguette slices and place Mozzarellissima slices on the remaining. Grill, covered, for 1 minute, or until cheese starts to melt.
